Sheffield Tramway was an extensive tramway network serving the city of Sheffield and its suburbs. The first tramway line, which was horse-drawn, started in 1873 with the opening of a line between Lady's Bridge and Attercliffe. This line was subsequently extended to Brightside and Tinsley. Routes were built to Heeley, where a tram depot was built, Nether Edge and Hillsborough. In 1899, the first electric tram ran between Nether Edge and Tinsley. By 1902 all the routes were electrified. By 1910, the Sheffield Tramway network covered 39 miles, in 1951 the network was extended to 48 miles. __TOC__
